Rated 5 out of 5 by risans use correctly
better than capsules and needs to be held in mouth/under tongue for best & fastest results - stomach acids reduce effects. Could be less sweet, but much better than unsweetened - taste very good overall

Rated 3 out of 5 by itech67 Way too sweet
I haven't been taking it long enough to judge it's effectiveness...
However, it is way, way too sweet. It is sweetened with stevia and has too much. I almost can't get past it.

Rated 1 out of 5 by Samuel13 taste terrible
Bought this thinking it would be more convenient than taking the same in tablets. was I wrong. The taste is terrible, absolutely terrible. Much too sweet , Taste like sugar in water. Nothing I could do could make it taste better.. Quit taking after a week, could no longer stand the taste. Thinking of calling Swanson for a refund. and see if they stand behind their guarantee. I would NEVER buy this again, Anyone interested in 3/4 container for free???

Rated 4 out of 5 by lou Combine with C and MSM powders
Sweetness masks bitterness of MSM, which is a good thing. However, I find it a little TOO sweet.

Rated 5 out of 5 by tony3461 Best Arginine product for the price!!!
This is actually the best tasting arginine powder out there!!! Not only that, it helps me during my workouts, with it I do more and last longer, no mistake about it. Before this, I used the GNC Pro Performance Arginine 5000 which was just as good except now they have discontinued it. That makes this my true favorite. And the price is great. No complaints.

Rated 5 out of 5 by Davidio None Better
Before purchasing this product, I read all the reviews. Bought it, loved it. For those who found it hard to tip the can to get at the powder at the bottom, I suggest you use a teaspoon. That is the volume of the scoop. You are welcome.
Thank you, Swanson's

Rated 3 out of 5 by spartanhealth don't like the taste
This is a good value for the level of arginine that you receive but I do NOT like the artificial sweeteners. I cannot cover up the taste when I mix this in my lemon water. Would not buy this agin, I'll have to check if they make an unsweetened version.

Rated 5 out of 5 by friendlyadvice Best Value Ever
The easiest way I have found to take Arginine. I love the sugar free bonus also. Swanson was a blessing in value for the money , as this was the best price I could find for such a high quality item. This is on my favorites list and I will be a regular customer from now on.

Rated 4 out of 5 by kilgz If you are like me & like to use a Powdered Form of Arginine, this is the BEST I have found. Price as well as taste is uncomparable to others & very acceptable & easy to use. I add a small amount of fruit juice to make it even more tasty.

Rated 5 out of 5 by LesB Great taste
I have tried this product from health food stores and quite frankly they are like drinking putrid fish oil. This product is quite pleasant tasting and is a much needed improved tasting Arginine.

Rated 5 out of 5 by Jampony AWESOME
This is truly the best bargain from Swanson for Arginine AKG. The very first time I've had a scoop with some water, I was a little surprised by the taste. I wasn't sure if it was good or bad. By the the 3rd time glass, I was ready to make my own pre-workout lemonade concoction with this. Swanson Arginine AKG powder + Swanson Inositol powder-- y'all can figure out the rest. I highly recommend this product.

Rated 5 out of 5 by stayingyoung Not really sure what it's doing, but I take it with MSM and my overall energy level seems to get better. Haven't tried it alone yet.

Rated 5 out of 5 by Ericw2525 Awesome product
This product rocks.! I enjoy this wonderful lemon taste and you do not even know it is arginine. I find that if I take 5grms one scoop 1 hr before workout it allows long lasting strength and if you take 3 to 4 scoops even better. To me it is not harsh on the stomach but in high doses to other maybe like diarrhea. So start at one scoops and test it out. So many benefits from arginine. If you take this at night 1 hour before sleep try to take 15 grams and if you take orthine with this at 5 grams you have a great little stack to release natural growth hormone from your own body. it will help you sleep better and recovery and help with building lean muscle. Do it for a month then take a couple weeks off then continue over and over again works great become younger from the inside out.

Rated 5 out of 5 by merrysunshine super taste
I love the flavor and quality of this powder. I would like to see this formulation include citrulline as well though so I wouldn't have to take it separately. This helped me get through 4 hour physio sessions.

Rated 5 out of 5 by coolrunr Taste and effect are "Wow"
The great taste of this powder encourages its use prior to body building. It mixes easily in water and, most importantly, is truly effective in energizing me!

Rated 5 out of 5 by gitfit50 best tasting
I am completely happy with my purchase of this product from Swanson because of the taste. I've tried other arginine powders that are completely undrinkable. I love the taste of this product and the pump I get during my workouts with it.

Rated 4 out of 5 by JGee The Arginine AKG powder is a good product. The lemon flavor is pleasant. I use in conjunction with citrulline malate powder. Great pumps during workouts.

Rated 5 out of 5 by coolbeans7 akg powder
this product is a good dosage and good price, for what you get, plus no artificial sweetners is a bonus. I have been taking typical preworkout formulas for years and they never put the amount of each ingrediant on the label. From now on i will be buying form here, at least i know what im getting. I have noticed good results from this product as well.
